DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-4, a generating system in accordance with the preferred embodiment of the present invention comprises a first generating device 1 and a second generating device 2.

The first generating device 1 includes a housing 11, a solar cell panel 12 mounted on an open upper end of the housing 11 to receive a solar energy and to convert the solar energy into an electric power and a thermal energy, a storage unit 13 connected to the solar cell panel 12 to receive the electric power of the solar cell panel 12, a heat conduction layer 16 mounted in the housing 11, a heating chamber 14 formed in the housing 11 and located between the solar cell panel 12 and the heat conduction layer 16 to receive the thermal energy of the solar cell panel 12, a plurality of water pipes 15 mounted in the heating chamber 14 of the housing 11 and contacting with the heat conduction layer 16, a plurality of warming pipes 151 mounted in the heating chamber 14 of the housing 11 and surrounding the water pipes 15 respectively, and a thermal insulation layer 17 mounted in and abutting a bottom of the housing 11.

The housing 11 has a substantially U-shaped cross-sectional profile. The heating chamber 14 is located between and sealed by the solar cell panel 12 and the housing 11. The heat conduction layer 16 is located between the water pipes 15 and the thermal insulation layer 17. The heat conduction layer 16 is made of metallic material having a greater heat conduction effect, such as a copper to enhance the heat conducting effect of the water pipes 15. The thermal insulation layer 17 is located between the heat conduction layer 16 and the bottom of the housing 11 to provide a thermal insulation effect and to prevent a heat loss. The storage unit 13 is located outside of the housing 11, and the electric power of the solar cell panel 12 is delivered to and stored in the storage unit 13. Each of the water pipes 15 is made of metallic material having a greater heat conduction effect, such as a copper. Each of the water pipes 15 is received in the heating chamber 14 and is located between the solar cell panel 12 and the heat conduction layer 16. Each of the warming pipes 151 has an inner portion containing a warming liquid 152. Thus, the water in each of the water pipes 15 is warmed by the warming liquid 152 in each of the warming pipes 151.

The first generating device 1 further includes a water storage tank 18 mounted on the housing 11 and connected to each of the water pipes 15 to form a water circulation between the water storage tank 18 and the water pipes 15, a heat storage tube 182 mounted in the water storage tank 18, and a helical warming tube 181 mounted in the water storage tank 18 and surrounding the heat storage tube 182. The water storage tank 18 is located outside of the housing 11 and has an inner portion containing water. The heat storage tube 182 has an inner portion containing a heat storage liquid 184, such as heavy oil, asphalt and the like so as to save the heat energy efficiently. The warming tube 181 has an inner portion containing a warming liquid 183, such as an oil and the like.

The second generating device 2 is mounted on two opposite sides of the housing 11 of the first generating device 1 and includes an impeller 21 rotatably mounted on the housing 11 of the first generating device 1, a propeller shaft 22 mounted on a central portion of the impeller 21 to rotate in concert with the impeller 21, and a generator 23 connected to the propeller shaft 22 to receive a power transmitted by the propeller shaft 22 so as to generate an electrical energy.

The impeller 21 of the second generating device 2 has a windmill shape and is disposed at a horizontal state. The impeller 21 of the second generating device 2 is located above each of the water pipes 15 of the first generating device 1. The impeller 21 of the second generating device 2 partially protrudes outwardly from the housing 11 of the first generating device 1 so that the impeller 21 of the second generating device 2 is rotated by the wind power or water power. The propeller shaft 22 of the second generating device 2 is disposed at a horizontal state and is located at a height the same as that of the solar cell panel 12 of the first generating device 1. The generator 23 of the second generating device 2 is located beside and connected to the storage unit 13 of the first generating device 1 to transmit the electrical energy to the storage unit 13 of the first generating device 1.

In operation, referring to FIGS. 5 and 6 with reference to FIGS. 1-4, the generating system is mounted on the top of a building 5 and is disposed at an inclined state. In such a manner, when the solar cell panel 12 of the first generating device 1 receives a solar energy, the solar cell panel 12 can convert the solar energy into an electric power and a thermal energy. Then, the electric power of the solar cell panel 12 is transmitted into and stored in the storage unit 13. Thus, the electric power stored in the storage unit 13 can be supplied to the building. In addition, when the solar cell panel 12 converts the solar energy into the electric power, the solar cell panel 12 will produce a thermal energy which is filled with the heating chamber 14 of the housing 11 to heat the water pipes 15 so as to heat the water flowing through the water pipes 15. At this time, the heat conduction layer 16 can enhance the heat conducting efficiency of each of the water pipes 15 by a heat conduction effect of the heat conduction layer 16. Preferably, the solar cell panel 12 is transparent to expose each of the water pipes 15 outwardly so that the solar light is directly projected onto each of the water pipes 15 to enhance the heating efficiency of each of the water pipes 15. In addition, when the water temperature in each of the water pipes 15 does not reach the required value, the electric power stored in the storage unit 13 can be supplied to heat the water in each of the water pipes 15. Thus, the first generating device 1 can receive the solar energy to produce an electric power that is transmitted into and stored in the storage unit 13 and a thermal energy that is used to heat the water in each of the water pipes 15.

Alternatively, when the wind blows on the top of the building 5, the impeller 21 of the second generating device 2 is rotated by the wind power as shown in FIG. 5 to produce a power to the propeller shaft 22, and the propeller shaft 22 transmits the power produced by rotation of the impeller 21 to the generator 23 so as to generate an electrical energy which is delivered to and stored in the storage unit 13 of the first generating device 1. Alternatively, when the rain drops onto the top of the building 5, the impeller 21 of the second generating device 2 is rotated by the water power as shown in FIG. 6 to produce a power to the propeller shaft 22, and the propeller shaft 22 transmits the power produced by rotation of the impeller 21 to the generator 23 so as to generate an electrical energy which is delivered to and stored in the storage unit 13 of the first generating device 1. Thus, the second generating device 2 can generate an electrical energy by the wind power and the water power when the solar energy disappears at the night. In addition, when the impeller 21 of the second generating device 2 is driven by the wind power or the water power, the impeller 21 of the second generating device 2 is rotated at the same direction, so that the impeller 21 of the second generating device 2 is rotated more rapidly when both of the wind power and the water power exist so as to enhance the generating efficiency.

As shown in FIG. 7, the heat energy from the sunshine is transmitted through the water storage tank 18 and the warming tube 181 into the heat storage tube 182 and is stored in the heat storage liquid 184. At the same time, the warming liquid 183 in the warming tube 181 can also absorb the heat energy and transmits the heat energy to heat the water in the water storage tank 18.

As shown in FIG. 8, when the sunshine disappears, the heat energy stored in the heat storage liquid 184 of the heat storage tube 182 is transmitted to the water storage tank 18 to heat the water in the water storage tank 18.

Accordingly, the first generating device 1 can receive the solar energy to produce an electric power, and the second generating device 2 is driven by the wind power and the water power to generate an electrical energy so that the generating system can use the natural resources to produce an electrical energy at the day and the night so as to enhance the generating efficiency of the generating system. In addition, the first generating device 1 can receive the solar energy to produce a thermal energy that is used to heat the water in each of the water pipes 15 so as to produce hot water for a household purpose. Further, the generating system is mounted on the roof of a building 5 easily and conveniently, thereby decreasing the costs of assembly. Further, the impeller 21 of the second generating device 2 is disposed at a horizontal state so that the impeller 21 of the second generating device 2 will not fall down due to the wind.

It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
